This Coachmen Prism 2150CB motorhome, built on a 2018 Mercedes Sprinter 3500 chassis, is now going back to the dealer a third time for the same problem. First time, rear wheel speed sensors were replaced while in for other service as a part of a recall. No big deal. But apparently the issue is not isolated to rear wheel speed sensors. At 11k miles, 500 miles from home, another wheel speed sensor went out, this time the left front. Now, at 14k miles, 1500 miles from home, the right front wheel sensor went out. When this occurs, the following systems do not work: ABS, ESP, cruise control. Why were ALL wheel speed sensors not included in the recall?
